Air fryers have become common fixtures in modern kitchens, appreciated for their speed, crispy results, and minimal cleanup. Many households keep them on the counter, plugged in and ready to use at any time.
That everyday convenience, however, can mask a small but preventable safety concern. Air fryers are powerful appliances that produce high heat and draw consistent electrical current during operation.
Even once switched off, some internal parts may remain warm. As time passes, cords, plugs, and outlets can deteriorate internally without obvious external signs. Like all electrical devices, air fryers can develop hidden wear or electrical issues.
When an air fryer remains plugged in, it stays connected to the home’s electrical system. In rare cases, factors such as power surges, internal failures, or lingering electrical flow may cause overheating. Many kitchen fires don’t begin dramatically but instead develop gradually due to stressed wiring, grease accumulation, or overheated components.
Where the appliance is placed also matters. Air fryers are often positioned near other devices, cabinets, paper products, or fabric items. Restricted airflow and nearby flammable materials can allow even minor problems to escalate more quickly.
Grease buildup is another commonly overlooked issue. Regular use can release fine oil residue that settles in vents and around heating elements, increasing risk when combined with heat and electricity.
For these reasons, safety professionals advise unplugging air fryers when they are not in use. Completely disconnecting the appliance helps reduce exposure to electrical surges, internal malfunctions, or accidental activation—especially overnight or when no one is home.
Simple habits go a long way: clean the appliance routinely, inspect cords for damage, ensure proper ventilation, avoid extension cords, and plug directly into wall outlets. Air fryers themselves aren’t inherently dangerous, but unplugging them after use is an easy step that can lower unnecessary risk and provide added peace of mind.
